That's odd. What browser are you using?
After the reboot last night, I went into the campaign tab and got through all the rooms fine. Then I went to the lair and there were two dragons there. After defeating the first one it told me I had won. There was only supposed to be one dragon. Update-- It's still going on. When you go to the lair, there are always two dragons only one of which you can defeat. Any idea when this will be addressed?
